Description

Gastric Mucin CAS NO 84082-64-4 is a high-purity glycoprotein complex derived from the mucosal lining of the stomach. This compound is essential for research and development in life sciences due to its unique biological properties and role in mucosal protection. It serves as a critical raw material for pharmaceutical development, diagnostic reagent formulation, and advanced biomedical research, meeting the stringent demands of global B2B clients.

Application

• Pharmaceutical Excipient: Used as a bioadhesive agent and protective coating in gastro-retentive drug delivery systems.
• In Vitro Diagnostic (IVD) Reagents: Serves as a key component in immunoassay buffers and calibrators to reduce non-specific binding.
• Gastrointestinal Research: Employed as a standard or substrate in studies of gastric barrier function, Helicobacter pylori adhesion, and mucin biology.
• Cell Culture & Tissue Engineering: Used to coat surfaces to enhance cell attachment and mimic the natural extracellular matrix for specialized cell lines.
• Nutraceutical & Cosmetic Formulations: Incorporated into products designed for gastrointestinal comfort or as a moisturizing and protective agent in topical applications.
• Biomaterial Development: Investigated for creating mucoadhesive films, hydrogels, and other advanced biomaterials for medical devices.
